The evolution of carbon fixation: Studying Form I Rubisco using ancestral sequence reconstruction...

Presented By: Luca Schulz
Speaker Biography: I am a graduate student at the Max Planck Institute for Terrestrial Microbiology in Marburg, Germany under shared supervision by Georg Hochberg and Tobias Erb. My research focuses on understanding the evolution of protein complexes, particularly the carboxylase Rubisco that assimilates most inorganic carbon from the atmosphere.
Webinar: The evolution of carbon fixation: Studying Form I Rubisco using ancestral sequence reconstruction and mass photometry
Webinar Abstract: Up to now, the evolutionary trajectory of the most prevalent CO2-fixing enzyme - Rubisco Form I, has been difficult to study. The Rubisco found in today’s plants and algae has 8 small subunits (SSU) that are absent from its ancestral form. The SSU has become essential for the enzyme’s solubility and activity, hindering biochemical studies into its influence on Rubisco. Our research aimed to decipher how the obligate interaction between Rubisco and its SSU evolved.
